1. When doing a gram stain procedure, what color is agram-negative cell after decolorized has been added?
a. it will be a dark purple color
b. it will be a pink color
c. it will have no color
2. In the acid fast staining procedure, why does the methyleneblue not add to the cell’s layers and create a purple color
a. the phenol in carbolfuchisn prevents mixing with methyleneblue
b. a non-acid fast cell ( acid fast negative) will have alreadylost the pink carbolfuchsin
c. an acid fast cell (acid fast positive) will have a myceliaacid layer that keeps the methylene blue out the layers
3. In the spore stain, what is the mordant in thisprocedure?
4. in the spore stain, why does the spore not stain red like thecell?
a. the spore is too small to take on a stain
b. all of the options are correct.
c. the spore has many layers of protection that keep chemicalsout
d. the spore didn’t have enough time to release the green totake on the red stain
5. what genus of bacteria can be identified by a spore stainprocedure?
b. bacillus or clostridium
c. we won’t be able to tell
d. bacillus only
6. If we identify spores on a stain slide, what type ofenvironment were the cells in before the stain procedure to seethese results?
a. the cells were in an unfavorable environment to createspores
b. the environment is not a factor in the spore formation
c. the cells were in a favorable environment to createspores
7. if we do a spore stain procedure and we see circular redcells, what do we know about these cells?
a. circular cells will tell me that these may be bacillus orclostridium
b. these cells will not make spores
c. circular red cells means that the spore lost their sporecoat
8. what do we know about the cells that stain pink in a gramstain procedure?
a. pink cells means that they are gram positive
b. we will know their cell wall type only
c. we will know their cell wall is negative, we could also seeshape and arrangement
